1.1.3-beta

Allow import of shared-riff metadata snapshots to switch offline user. Small fixes for obscure jam name exports. Bring back the Jam Browser, but offline now. Small change to how Solo/Mute works to better suit how I want it.

NOTE: for Windows users, you may have to update your Visual Studio runtimes if LORE/BEAM immediately close when you try launching them. The latest installer is included in the Windows package below, or download and run it direct from Microsoft https://aka.ms/vs/17/release/vc_redist.x64.exe
